To all whom it may concern:

Be it known that I, V 1011 i-l. liter re, a citizen of the United States, and e resident :of the city of New York, borough of Manhattan, in. the county and State of New York,

"have invented a new and useful improvea sound waves passing through it 1s also a clamping engagement therewith l mentin Phonograph llorn's, of "which the following is a full, clear, and exact description. v The pur s collepsib e phonograph born or megephonc, wherein the sections can be completely se sm'stod one from the other, end compactly nested, and to provide simple means for drawing the sections together, which means can be quickly and conveniently applied or removed.

' It is a further purpose of the invention to so construct the horn'thst the vibrations-will not be carried from one section to the other, and whereby the vibrations will be extremely light and will in no mannerinterfere with the the horn; and purpose oi the invention to so construct the urn that there will be absolutely no rettling wheu the horn is set up and in use. I

The invention consists in the novel construction and combination of the severel parts as will be hereinafter fully set forth and pointed out in the claims.

' Reference is to be had to the accompany ing drawings forming a part of this specification, in which similar characters of reference indicate corresponding ports in all the figures.

I Figure 1 is. a longitudinal section through the improved horn, showing one tie rod simply fitted thereto and at second enlarged section through portions of opposing body sections of the horn, illustrating the manner in which one section. is fitted to the other; Fi 3 is a view similar to that shoivn in Fig. 2, but illustrating the form of connection employed between the inner or most contracted body section and the section next thereto; Fig. 4 an enlarged transverse sec tion through a portion of ti keeper employed lor the locking ing a form or a or clamping devices for the body sections ol the horn; Fig. 5 is a longitudinal section through the body section of the horn, showing the said body sections nested; and l11g. 6 is a sectional side elevation of one of the tie rods, showing a modified construction.

'05s of the invention is to provide tie rod in 1g. 2 is on is born, illustrate nc horn is made up of sections A, an desired number of sections being employer, and the said sections are usually of the some depth except the most contracted or innermost section that is designated as A. When the sections or members of the horn are assembled they lie in close engagement one with the other, and while various means may be employed for eil'ecting a connection between opposing sections of the horn, the means shown in detail in Fi e. 2 and 3 are those that are preferred. it will be distinctly understood that the sections of the horn in no manner telescope each other, but their opposing edges rest flatly and smoothly one against the other, and inliolding the sections of the horn assembled they are drawn together by clamping devices to be hereinafter described.

Each body section A is provided with a, hub 10 at one end and an outwardly extending llo-ngc ll at the opposite end, the flange of one section being neatly received inthe hub of an opposing section, but a slightly different form of connection is provided between the inner section A of the horn s'md the next section thereto, and this connection is illustrated in Fig. 3, and may be used for all the sections and consists in providing an angular flange 1'2 at the oiiter edge of the forward end portion. of the said section A,

After the sections of the horn have been rods are made to engage with the connection between the forward section A and the sec tion next thereto, and the opposite ends of the tie rods are made to engage with the flange 12 at the head 13 thereon, as is shown in Fig. l. The tie rods B are made of such length that when they have been sprung into the position just described, they are tight and will hold thee-actions of thehorn together, but in order that the said sections may be positively drawn and firmly held in en gcgenient one with the other, the tie rods B n einst which angular flange 12 the flange 11 assembled, one of the hooked ends of the tie are sprung inwardat'their' central portions so as to lie against 'the exterior of the horn cdnformin to its exterior contour, as is shown in ig. 1, and the tie rods are held in this position-by passing them beneath keepers 15, usually formed on the exterior of one oft-he sections of the horn, and these keepers 15 are preferably in the form of hooks, clearly-illustrated in Fig. 4, and where the rods and keepers engage either one or the other may be insulated so as to prevent the rods from vibrating or conducting vibrations I from one section to the other.

The tie rods B shown in Fig. I are plain, that is to sav they are made from one piece of material, ut it is sometimes desirable to employ the type of rod B shown in Fig. 6,

wherein the rod is provided with an exterior thread 17 at, each and, one thread being a right-hand thread and the other a lef -haml thread, the threaded end of a tie rod is received in a correspondingly threaded sleeve 18, and each of the said sleeves 18 is provided with a hook 19 at its outer end. The tie rods B are. applied in the some manner as the tie rods B and are also held to'the body of the horn hv keepers 15, but in the form of the tie rods B the saidrods may he lengthened or shortened to adapt them to horns of different length.

It is eviderit that a horn of the character described can be quickly and conveniently built up and locked in its set-up position, and

that by sim ly loosening and removing the tie rods emp oyed the sections of the body or" the'horn will separate and can he nested, as

. is shown in Fig. 5, and packed in an exceed inglysmall compass. I desire it to be understood that insulating material may also he employed when the ends of the rods engage the sections of the horn.

Having thus described my invention, claim as new and desire to secure by Le tter. Patent,-
